TMTT,
You are still correct, turtles don't have ears. If I can find a bigger picture of the sides of their heads there are red sections where ears might be and that is how they got their name. Believe it or not turtles can be rather entertaining. They eat anyting and everything that might fall in their aquarium. For exercise give them feeder fish for them to try and catch. Kinda entertaining in a macabre sort of way.
